On the first day, you need to install Eclipse and the Spoofax language workbench.

Installation

We highly recommend to work with a fresh Eclipse installation. You may also install some additional Eclipse plug-ins to which you are used to, e.g. for version management.

Initial Project

We recommend to start with an empty Eclipse workspace. Import the initial project^? using the Import > General/Existing Projects into Workspace wizard. Build the project by selecting it and choosing Project > Build Project from the menu. The console will report success or failure.
